The Jewish Agency’s immigration department disclosed today that it was seeking additional hotel space in Vienna to accommodate Russian Jews arriving there on their way to Israel. It also said that it would expand its staff because the larger number of Jews arriving from the Soviet Union required additional personnel to receive them. Department head Uzi Narkiss is presently in Vienna to survey the needs, Jewish Agency sources said. “The preparations in Vienna are under control,” he noted. “Should there be an influx of Jews from Russia we shall be able to handle them.” Narkiss said he was moved when Soviet Jews, arriving in the city, toasted to the life of Israel and when many cried remembering the millions of Jews that are still in the Soviet Union.
